The burgeoning field of small satellite technologies is revolutionizing astrophysical observations, democratizing access to space-based astronomy through miniaturization, cost-effectiveness, and rapid development cycles. These platforms, including CubeSats and nanosatellites, are enabling sophisticated scientific investigations across various wavelengths, from X-ray to optical and radio astronomy, with key applications in wide-field surveys, exoplanet characterization, and solar physics [1].
The development of advanced sensors and miniaturized optics is paramount for achieving high-performance astrophysical instruments on small satellites. Innovations in focal plane arrays and compact telescope designs are crucial for maintaining scientific rigor while adhering to stringent mass and power constraints, paving the way for missions that challenge the scientific output of larger observatories [2].
Onboard data processing presents a significant challenge for small satellites due to limited computational resources. Efficient algorithms and hardware architectures for real-time data analysis and reduction are essential, employing techniques for intelligent data compression and targeted data downlink to optimize scientific return and manage bandwidth limitations [3].
